Hewlett-Packard is laying off as many as 525 employees in connection with its plans to ax its WebOS hardware business, according to a report.

AllThingsD's John Paczkowski says sources told him the pink slips began going out this week and that HP confirmed the layoffs with a statement reading, in part, "the WebOS GBU is undergoing a reduction in workforce." The company would not say how many workers were being let go, Paczkowski says.
